英文摘要	采用流式细胞仪对2009年春季东海、黄海浮游病毒和异养细菌的丰度进行了大尺度(119.5°—129°E,25°—39°n)研究,并分析了浮游病毒丰度、异养细菌丰度以及其与环境因子之间的相关性。结果表明,研究海域浮游病毒、异养细菌的丰度范围分别为3.38x105—2.26x107个/Ml(平均6.24x106个/Ml)、5.83x103—1.23x106个/Ml(平均1.22x105个/Ml)。在水平分布上,浮游病毒与异养细菌的变化趋势基本一致,且均在山东半岛周边养殖海域、浙江东南沿海养殖区及舟山渔场北部形成明显的高值区;黄海浮游病毒与异养细菌的丰度平均值均高于东海。在垂直分布上,东海浮游病毒与异养细菌丰度值随水深呈明显下降趋势,表层丰度值与30M以下各层差异显著(P<0.05);在黄海,二者丰度随水深降低趋势不明显。PEArSOn相关性分析显示:调查海域浮游病毒丰度与异养细菌丰度显著正相关(r=0.288,P<0.01),浮游病毒丰度与温度显著负相关(r=0.243,P<0.05),异养细菌丰度与盐度显著负相关(r=0.245,P<0.05)。; We collected seawater samples in May 2009 from the Yellow Sea and East China Sea(119.5°—129.0°E, 25°—39°N) to determine the abundance distribution of virioplankton and heterotrophic bacteria with flow cytometer, and studied the correlation between the abundances of virioplankton and heterotrophic bacteria and environmental factors.Re- sults show that the abundances of virioplankton and heterotrophic bacteria ranged 3.38×105—2.26×107/mL(6.24×106/mL on average), and 5.83×103—1.23×106/mL(1.22×105/mL on average), respectively.The distribution pattern of virioplankton abundance was consistent with that of bacteria in horizontal direction and showed high-abundance areas around the coast of Shandong Peninsula, the southeast coastal region of Zhejiang Province, and the north region of Zhoushan Fishery.And the viral and bacterial abundances in the Yellow Sea were significantly greater than those in the East China Sea.The abundances of both virioplankton and heterotrophic bacteria decreased significantly with depth in East China Sea and that in the surface layer were significantly different from that of layers below 30m(P<0.05).The vertical distribution trend of abundances in the Yellow Sea was not obvious.In the investigated regions, the virioplankton abundance was significant positive correlation with heterotrophic bacteria(r = 0.288, P<0.01), and negative with the temperature(r = 0.243, P<0.05).The bacterial abundance showed negative correlation with the salinity(r = 0.245, P<0.05).; 国家自然科学基金项目资助;41076088号
